IMAP_Authenticatable Problem

Rails
1

Good morning all,
I’ve been using the imap_authenticatable plugin for about a year now
without
incident. All of a sudden, I tried logging in this morning and this
error is
showing up in the logs. Does anyone have any idea what could be causing
this
or how to fix it?

Thanks,
Pete

Well, I have no experience with imap_authenticate, but you need to
look at this line 52 in the plugin’s code to see what is the ‘nil’ and
then find where that gets set. Chances are there’s a condition that’s
not being properly checked for and the connection is never made; then
when some later error happens, the cleanup to disconnect is getting
called on the never-successfully opened instance.

Hi Rob,
Thanks for your answers. I switched the server from our authentication
server over to our mail server and it seems to be running fine, so I’m
assuming it’s an issue with the way the auth server handles IMAP/POP
authentication. Here’s the code from the plugin:

    def authenticate(username, password)
      imap = Net::IMAP.new imap_authenicatable_options[:host],

imap_authenicatable_options[:port], imap_authenicatable_options[:ssl]
username = clean_username(username)
imap.authenticate(‘LOGIN’, username, password)

      if imap_authenicatable_options[:allow_new_users]
        find_or_create_by_username(username)
      else
        find_by_username(username)
      end
    rescue
      false
    ensure
      imap.disconnect
    end

Does it sound like it’s an issue with the auth server to anyone else?

I’d say that a guard was needed on the disconnect call.

imap.disconnect unless imap.nil?

    end

With that naked rescue, it’s hard to say what the real problem is, but
I suspect a connection problem over an authentication problem.
